.SPECIFICATION forming partof Letters Patent No. 720,303, dated February 10, 1903. Application filed May 28, 1902. Serial No. 109.354. (No model.)

T 0 a/ZZ whom t muy concern:

Be it known that I, CHARLES FREMONT WILSON, a citizen of the United States, residing at Catlettsburg, in the count-y ofBoyd and State of Kentucky, have invented a new and useful Gas-Burner for Stoves, of which the following is a specification.

This invention relates to a novel gas-burner for gas-stoves, and while applicable for usein various connections is designed with special reference to the equipment of that class of stoves exemplified in my concurrent application, Serial No. 109,355. Stoves ofthis character are designed to utilize a uid fuel-as, for instance,natural or artificial gas--and primary considerations are economy in manufacture and the complete consumption of the fuel to prevent the smoking of the stove.

My object, therefore', is to produce a burner of inexpensive construction which may be composed almost entirely of cast parts capable of 'being quickly assembled Aand readily disorganized by an unskilled person.

A further object of the invention is to produce a novel arrangement of parts which will insure the proper mixing of the gas with a suitable quantity ofV air to form a perfectly combustible vapor the combustion of which will not be accompanied by the liberation of noxious gases or the production of any considerable quantity of smoke or soot.

To the employment of the objects stated and others subordinate thereto the inventionV consists in those features of construction and arrangement which will be hereinafter described, illustrated in the accompanying drawings, and succinctly defined in the appended claims. n

In said drawings, Figure 1 is a perspective view of my burner complete, the position of the guard-plate being indicated in dotted lines. Fig. 2 is a longitudinal sectional View. Fig. 3 is a plan view with the 4tube-plate removed, and Fig. 4 is a transverse sectional view on the line 4 4 of Fig. 2.

Like numerals of reference are employed to designate corresponding parts throughout the views.

The receiver 1 is in the form of an oblong or trough-shaped receptacle, preferably constructed of cast' metal and formed with feet 2, which hold the receiver, slightly elevated above the bottom of the stove or other supporting-surface to' permit a free circulation of air. Around its upper edge the receiver is provided with a transversely-angular flange 3, constituting a seat for the edges of a jetplate 4, closing the upper side of the receiver, and provided with a longitudinal series of jet-openings 5. lt is of course essential that this jet-plate be retained in a manner to prevent the escape of gas around the edges thereof. I therefore provide what may be termed a clamping-frame 6, seated upon the jetplate 4 and fitting Vsnugly within the upstanding portion or rim 7 of the angular iiange 3.. The clam ping-frame isof skeleton or open form, as shown in Figs. 1 and 4, so as to eX- pose the middle portion of the jet-plate, in which the'jet-openings 5 are formed. The means for retaining the clamping-frame and for drawing the same down to effect a tight joint between the plate 4 and the walls of the receiver may be varied within wide limits,

Vbut a simple construction and one which facilitates the assembling of the parts is shown in the drawings.

The clamping-frame is formed around the edges thereof with an angular ange 8, fitting over the upstanding portion 7 of the flange 3, and at its opposite sides is formed with laterally-disposed ears or lugs 9, disposed over similar ears or lugs 10, extending from the opposite sides of the receiver and disposed below cut-away portions or recesses 1l,formed in the-u pper edges ofthe fiange 3 for the accommodation of the ears 9 of the clampingframe. The coincident ears of the clampingframe and receiver are designed for the reception'of draw-bolts 12, passed through the ears and retained by nuts 13, which latter when screwed up serve to draw down the clamping-frame with sufficient force to effecta close joint between the jet-plate and the upper edge of the receiver.

At the opposite ends of the receiver the flange 3 is extended somewhat beyond the vertical portion, as indicated at 14, for the reception of the similarly-'extended ends 15 of the clamping-frame. The extension of these ends is designed for the accommodation of angular rests 16, formed upon and preferably cast integral with the clamping-frame and designed to interiittingly receive the terminal supporting-fianges 17 of a tube-plate 1S. The tube-plate is elevated a sufficient distance above the jet-plate 4 to define an intermediate mixing-chamber 19, open alongits opposite sides and designed to permit the jets of gas issuing through the jet-openings 5 to commingle with a sufficient quantity of air to form a highly-combustible vapor supplied to the burner-tubes 20, extending vertically from the tube-plate 18 and located directly above the jet-openings 5. (See Fig. 2.)

The tube-plate, as shown in Fig. 2, is retained in position b y the interfitting ofthe supporting-fianges 17 with the angular rests 16 of the clamping-frame and is held down in proper position by draw bolts 21, passed through the ends of the tube-plate and through the end flanges of the clamping frame and receiver, respectively, and secured by nuts 22 in an obvious manner. It will thus be seen that the entire assemblage of parts are so proportioned that they interfit without special adjustment and are secured in place by the bolts 12 and 21, which may be quickly and conveniently removed when the disorganization of the parts of the burner is desired for the purpose of replacement or repair.

NVhile the burner-tubes may be secured to the tube-plate 1S in any suitable manner,

they are preferably formed integral therewith, as shown, and are connected by integral webs 23, which serve to materially stiften the structure and to prevent the heat from warping the tube-plate or tubes, which would otherwise result in throwing the tubes out of proper parallelism and would interfere with the effective operation of the burner. This rigid retention of the tubes in proper position is further insured by what may be termed a guard-plate 24, having a series of openings 25, which permit the plate to be passed over the upper ends of the tubes and to be seated upon annular fianges 26, formed on each of the tubes for its support. This plate, while serving the purpose stated, also constitutes a guard which receives any small amount of sooty or oily deposit produced at the point of ignition. As this plate is removable, it may be quickly cleared of such deposits and replaced without necessitating the disorganization of the general structure, and the burner may thus be kept perfectly clean and in condition for effective operation with very slight attention.

The manner of feeding gas to the receiver 1 is immaterial; but a gas-supply pipe 27, leading from a suitable source of gas-supply, is preferably screwed into an inlet-opening 2S, which may be formed in one side of the receiver or at any other convenient point.

The operation of the burner is as follows: Gas admitted to the receiver 1 from the supply-pipe 27 will issue in jets through the jetopenings 5 and into the tubes. The proper amount of air drawn into the mixing-chainber 19, defined between the jet and tube plates, will commingle with the gas to form a highly-combustible vapor, which is ignited at the upper ends of the burner-tubes 20. Any sooty or oily accumulations at the points of ignition will drop upon the guard-plate 24, which may be readily removed and cleaned, as stated. It the disorganization of the entire structure is desired, it may be quickly effected by the removal of the several bolts 12 and 21, or if it is desired to remove the tubes and tube-plate without disconnecting the receiver, the jet-plate, and clamping-frame it will simply be necessary to remove the bolts 21 and lift the tube-plate from its rests.

It is thought that from the foregoing the construction and operation of my novel gasburner will be readily comprehended; but while the illustrated embodiment of the invention is believed at this time to be preferable I do not limit myself to the structural details defined, as, on the contrary, I reserve the right to effect such changes, modifications, and variations of the illustrated structure as maybe fairly comprehended within the scope of the protection prayed.
